Can't help on the specifics of taking the dash part out but the entire temp unit should be in one piece to be sent to an instrument repair shop for calibration or repair etc.

39 models are probably the same as most other years and share a mounting plate with another instrument. That plate unscrews from the cluster from the back and the pair of instruments remove. Once the plate is off, the temp gauge is held by a nut and can be separated from the other instrument by pulling the tube and sensor bulb thru the plate. The opening in the cluster may be odd shaped so the plate with instruments can need a bit of sliding and rotating for the instrument faces to clear. Just be careful so the needle or face isn't damaged during the maneuvering.

Most often it seems the bulb portion in the head is stuck and twists off when trying to remove is the main reason the parts become separated. John Wolf Instrument Repair is one company that has worked on many Packard gauges and comes recommended. They can install a new bulb or do whatever is needed on yours.
